ELECTRICAL coxmnorron AND Box.

i Application filed August 7,

' To all whom it may concern.'

Be it known that We, FREDERICK F. SKEEL,

a citizen of the United States, residin in f `larly applicable for use in connection with metersg and it consists inthe combinations and constructions hereinafter set forth and clairfied. In describing this invention reference is had` to the accompanying drawings, in which like characters designate correspondinparts in all the views.

1 re 1 is a longitudinal sectional view part y in elevation.

Fi 2 is an` end elevation looking upwar y in Fig. 1.

-Fi 3 is an end elevation looking up- Wardiy in Fig. 1,- the entrance piece being omitted.

Figs. 4 and 5 are sectienal'views taken, res ectively, on lines 4 4 and 5--5, Fig. 1.

igs. 6 and 7 are, respectively, a face view and a cross-sectional view o one of the blocks of insulation of the connection, said block being shown as inverted. Figs. 8 and 9 are views similar to Figs. 6 and 7 ofthe other block.

Fi s. 10,`11,' 12 and 13 are views similar to`F1gs. 6, 7, 8 and 9 of other forms of said blocks.

This electrical connection and box comprises, generally, a box having an opening in one side, an electrical connection including complemental blocks both having portions which extend into the opening of the box, 'and confine between them a Wire passage, terminals mounted on one of the blocks Within the passage, and means for holding the parts in assembled relation. It also usually includes an entrance piece common toboth blocks,

lis the box which is here shown as elongated in form and formed with an elongated opening 2 in one side thereof, the box also Speoieatlon o! Letters Patent.

having an internally threaded nipple 3 for connection with an electric conduit.

The box is also formedlwith extensions-18 projecting beyond the edge 6 at the open side 2 and located at the ends of the openingr 2 and the box. l

7 and 8 are the blocks of the connection, these blocks being formed of insulation and rnounted on the open side of the box and havin reduced portions 9, 10, whichl extend into t 1e box 1 through the opening 2. Por tions of the blocks 7, Salso extend beyond thc edge (i at the open side of thcbox and are of greater din'icnsions than the portions 9 and 10, and hence provide shonldersjll, l2 which rest on the edge (i. The bloclgs 7, 8 are separable from each other along a line extendin `longitudinally of the opening 2 and c on ne a plurality of wire passages 13 between them. i

The entrance piece is substantially thlc saine in plan `as a plan of the'outer end facef the combined blocks `7, Silrid isf4 formed with a niarginalbcad 17 onits rear f side which fits into a complemental rabbet,

on the ontercnds of the blocks 7 and 8i 18 are the extensions at Oppositeends of the box which inei0se` the rounding end portions, of the' blocks 7 and" 8 a'nrl the eil',-

trance piece 15. 19 is' a lockingbarcxtend ing transverselythrough the exllllllsionq18"` and engaging the outer face of tileentra Lce piece and preferably lying in a groovewQf n 2 nassaui the outer face of the entrance piece, this bar orderthat it may be readily seen if the con-` nections have Vbeen tampered with. Means ma f be also provided for locking-either or both of the b ocks 7 and 8 in position in order 4that they may not be dlsplaced when the entrance piece is removed, and as seen 1n Figs. 1, 2 and 3, a spring catch, such as thatshown at 22, maybe employed, this catch lying along the innerface of one of the'extensions 18 and bein fixed st one end, and having Iits 'other end ree and 1ts 1 ntermediate portion movable by its resiliency into a `roove 24 in one end of the blocks 7, 8, an'd eing movable out of the groove by pressing on the free end of the spring; or a spring catch, such as is shown at 25 may'be used, whichl catch is located at the outer side of one of the extensions 18 and has an engaging end or pawl 26 extending through an opening in said extension in 4position to coact with a notch in the end of the entrance piece 15. An suitable means maybe employed to ho d the blocks from displacement.

The passages 13, as shown in Figs. 1, 3, 4, 8 and 9, may be formed by providing ribs or barriers 27 on the block 7 on which the terminals are mounted, Whiltthppposing face of the block 8 is plain and engages .the

ends or tops of the barriers. However, as seen in Figs. 10, 11, 12 and 13, the barriers, as 28, 29, may be provided on both blocks 7, 8, each block having a portion of its face plain for engaging the barriers on 'the other lock. In operation, the entrance piece is arranged with the holes 16 out of alinement with the/passages 13 and when it is desired -to make connection with the terminals 14 the bar 19 is removed, thus .permitting the removal of the entrance piece and the block 8 and also the block 7 if desired, the block` '7 being removed asI far as the wires con- 'nected'to the terminals 14 from the interior' of the box will permit. The entrance piece is reversed so that when it is laced in position, the holes 16 thereof will aline with the passages 13. The meter wires are then passed throughthe holes 16 and connected to the terminals 1,4, the block 8 and also the' block 7, if it has been displaced, replaced in the box the entrance piece placed in position and the loeki bar passed through the nvtenzions' 18 and t e groove 20.
